Cross classification of census data for use in estimating residential heating demands
This report documents the procedures and assumptions used to cross classify 1970 census data for use in estimating residential heating demands on a small areal basis. The major results for all census tracts and minor civil divisions in the US comprise (1) counts of occupied dwelling units by building size, by type of space heat equipment, and by space heat fuel type; (2) counts of occupied dwelling units by building size and by water heat fuel type; and (3) the percentage distribution of occupied dwelling units in each building size category across four dwelling unit size categories. These reduced data, both at the tract/minor civil division level and aggregated county and state levels, are sufficiently accurate for systems and economic analysis of district heating and other residential energy conservation programs

Planning analyses for geothermal district heating
Methodology and data bases are described which can provide a comprehensive planning assessment of the potential for geothermal district heating in any US market. This economic systems model encompasses life-cycle costing over a period of rising competitive fuel prices, it addresses the expansion and financing of a district system over time, and it includes an overall optimization of system design. The elemental area for all analyses is the census tract, for which published data allow estimation of residential and commercial heating demands, building retrofit requirements, and competitive fuel consumption and cost. A system type design, an appropriate hot water district piping system, and costing of heat supply is performed for groups of contiguous tracts in any urban market. Groups are aggregated, in decreasing benefit to cost order, to achieve optimal systems. A specific application for Salt Lake City, Utah, is also described

Energy reserves. [Summary of reserve estimates and economic supply models for exhaustible resources]
There is an increasing concern about scarcity of the world's remaining natural energy resources and, in particular, the future supply of oil and natural gas. This paper summarizes recent estimates of energy reserves and economic supply models for exhaustible resources. The basic economic theory of resource exhaustion is reviewed, and recent estimates of both discovered and undiscovered energy resources are presented and compared. Domestic and world-wide reserve estimates are presented for crude oil and natural gas liquids, natural gas, coal, and uranium. Economic models projecting supply of these energy forms, given reserve estimates and other pertinent information, are discussed. Finally, a set of recent models which project world oil prices are summarized and their published results compared. The impact of energy conservation efforts on energy supply is also briefly discussed. 53 references
